"A more terrifying existence?!"

Linley’s eyes widened in disbelief, “Could it be a sacred beast?”

Doehring Cowart said in a deep voice, "We can't rule out this possibility... But since you've already come in, if you want to get out, you'll probably be surrounded by hundreds of dragon monsters. The final result will be death."

At this point, Doehring Cowart sighed and said with some self-blame, "It's all my fault for not observing this cave carefully. If you really encounter any danger later, I will use the last of my strength to protect you and let you escape with all your strength—"

"Grandpa Delin, look what I found!"

Linley suddenly spoke in surprise, interrupting Doehring Cowart’s words.

Doehring Cowart was slightly startled, and immediately turned his head to look behind him.

Linley took two or three steps to the corner of the deep cave, brushed away the dust on the wall with his right hand, and revealed a mark that looked like a dragon pattern.

"This is... the family emblem of the Baruch family?!"

Doehring Cowart couldn't help but exclaim.

Linley nodded and said with a smile, “Yes, that’s our family crest!”

"Grandpa Delin, thanks to you, I finally found the cave mentioned in my uncle's letter!"

Doehring Cowart came back to his senses and said thoughtfully, "You mean, this was left by Haven?"

“That must be it!” Linley nodded, stood up and looked into the depths of the cave, smiling, “My uncle mentioned in his letter that he killed a level nine peak Iron-armored Dragon in this valley, and then found a special dragon blood pool in the area guarded by the Iron-armored Dragon.”

"With the active dragon blood in the blood pool, he successfully activated his bloodline and became a dragon blood warrior."

At this point, Linley’s expression hardened, and he clenched his fists and said, “Now, I have received the Blue Heart Grass that my uncle sent me, and my physical body has also reached the peak of level eight. As long as I find that blood pool, I can awaken my bloodline and become a true dragon blood warrior!”

Seeing the determination and expectation on Linley’s face, Doehring Cowart felt relieved and couldn’t help but chuckle.

"This is truly... a blessing in disguise, a way out of a desperate situation!"

After saying that, Doehring Cowart straightened his expression and warned, "But don't be careless. It's better to be cautious. After all, what your uncle told you is outdated information from a few years ago. No one knows whether there will be another peak level nine creature here."

"Yes, I understand."

Linley nodded, raised his hand and touched Beibei’s head on his shoulder, then walked carefully into the cave.

Ten minutes later, Linley stood at the entrance of the broken hole in the ground, staring blankly at the hidden cave below that looked as if a large piece had been dug out.

"Blood... Where's the blood pool?"

"Where is the blood pool mentioned in my uncle's letter?"

Linley’s eyes widened as he stared at the empty hole beneath his feet with a look of despair.

After he learned about Haven's awakened bloodline five years ago, he made up his mind to first improve his warrior level and become a true dragon blood warrior.

So, he temporarily relaxed his practice of magic and trained hard for five years, until he set out three months ago, overcoming numerous hardships and dangers, and fighting his way into the Misty Valley, just to use the blood pool here to activate his bloodline.

But now when I got there, I found there was no blood pool?!

"Uncle!!!"

Linley clenched his fists tightly, and his handsome face was filled with a dark aura.

Bei Bei blinked his eyes, tucked his head into Lin Lei’s collar, and muttered, “The boss is angry. How scary~”

After a moment, Linley loosened his fist in frustration, looked at the dug-out mark below and smiled bitterly.

"Forget it, it's better to make a wasted trip than to lose your life..."

“Lin Lei, come over here and take a look!”

Doehring Cowart's solemn voice suddenly came from the side.

Linley was startled for a moment, and quickly turned his head. He saw Doehring Cowart’s soul floating in the center of the cave, looking up at the dark stone ceiling with a solemn expression.

Following his gaze, you can see a corridor with smooth inner walls, which connects this underground cave directly to the sky.

“…So there’s another entrance here!”

As Linley said this, he walked over to Doehring Cowart with a smile.

Doehring Cowart shook his head and said solemnly, "This is not an entrance. It is a trace left by a battle!"

"……What?!"

Linley opened his eyes wide and stared at the empty hole above his head in disbelief.

This hole or tunnel has a diameter of more than two meters, a smooth inner wall, and a length of more than seven hundred meters.

Such exaggerated marks were actually left by a battle between powerful people... Who could it be? Could it be my uncle? !

Just as Linley was thinking about this, Doehring Cowart said again, “This passage is not unusual. Any Saint-level warrior can do this easily. What I want you to see is the middle section of this passage.”

Linley was slightly startled. He followed Doehring Cowart’s gaze and saw a bulge on the smooth inner wall in the middle.

"…What is that?"

Linley opened his eyes wide and said in astonishment, “Such a powerful attack was actually unable to destroy that thing!”

Doehring Cowart said solemnly, "Although this is just the tip of the iceberg, I am roughly sure that this thing is a magic circle base!"

Linley understood instantly and asked in astonishment, “Grandpa Delin, are you saying that there is a magic circle buried in this mountain?”

"That's right." Dorinkovote nodded and said solemnly, "The reason why this cave is so dense with dark elements is probably because of this magic circle!"

“…”

Linley hesitated for a moment and asked softly, “Would you like to take a look?”

Doehring Cowart pondered, "As a magician who pursues the truth, my answer is that you must read it, because it may contain some profound magical knowledge that even I don't know. But as your grandfather Doehring, I suggest that you don't act impulsively for the time being. It's best to come back and study it carefully after you are promoted to a Sanctuary Magician..."

"Your uncle came here that year but didn't touch it. This should be the reason!"

Having said that, when Lin Lei heard the magical knowledge that even Grandpa Delin didn’t know, a look of hesitation appeared on his face.

Seeing him like this, Doehring Cowart couldn't help but fall silent.

The two of them remained silent for a long time, but finally they couldn't resist the temptation and started to pretend to dig, half-heartedly.

Soon, the solid stone wall of the ceiling melted and collapsed under the influence of earth magic, revealing a black dome hidden inside with countless intricate magical patterns engraved on its surface.

The magic pattern was so complicated that even the former Sanctuary magician Dohring Cowart couldn't help but reveal a look of shock when he saw the entire magic circle for the first time.

As for Linley, his magical attainments were far inferior to Doehring Cowart’s.

Therefore, after the black dome appeared, his attention was attracted by the purple sword inserted upside down in the center of the dome.

"...Such a restrained dark aura!"

Linley looked at the purple sword in amazement.

Doehring Cowart came back to his senses and carefully sensed the purple longsword. He stroked his beard and smiled, “Linley, you are indeed lucky. Although you didn’t get to see the blood pool, getting this purple longsword is no less than getting a Holy Domain Magic Crystal Core!”

"Holy Domain Magic Crystal Core?!"

Linley asked in surprise, “Is this purple sword so precious?”

Doehring Cowart nodded and smiled, “If I’m not mistaken, it should be a divine weapon from Hell, and divine weapons usually recognize their owners by dripping blood. Linley, drop some blood on it and see if you can take this divine sword!”

Linley nodded hastily, then pricked his finger, leaped forward, and touched the sword with his bloody finger.

In an instant, the purple sword that had been covered in dust for who knows how long began to tremble violently.

“Buzz~~”

The purple sword body absorbed the blood like a sponge, and then made a sword sound like a dragon's roar.

"It is indeed an ownerless thing."

Doehring Cowart showed a look of surprise on his face: “Linley, quickly pull it off!”

Lin Lei, who had just landed on the ground, jumped up again upon hearing these words, grabbed the hilt of the sword, and pulled it out violently.

“clang——”

The sound of a sword chiming was heard, and Linley landed lightly on the ground, holding the purple sword.

At this moment, a figure suddenly flew out from the corridor leading to the sky and crashed beside the two of them.

Linley was startled and immediately transformed his arms into half-dragons. Then, holding the purple long sword in his right hand, he looked at the figure beside him with a vigilant look.

“…Who is it?!”

"Um?"

"Uncle?!"

Before he finished speaking, Linley lowered his arms and looked at Haven with a look of surprise on his face.

At this time, Haven, who was already over 1.9 meters tall, stood up, looked at Linley and Doehring Cowart with a frown, and then cast his gaze towards the purple sword in Linley’s hand.

"He actually recognized his master..."

Haiwen sighed helplessly, then looked at Lin Lei and said, “Lin Lei, do you know what you have done?”

"This sword is a seal. If you pull it out now, the sealed thing inside... will come out!"

After hearing Haven’s words, Linley was stunned and could not help but turn his head to look at Doehring Cowart.

"Grandpa Delin?"

Dorinkovote nodded and whispered, "I know this sword may be a seal, but compared to the consequences of removing the seal, the benefits of obtaining this sword are greater. After all, this is the Monster Mountain Range. Even if there is danger, it will not endanger the human kingdom."

"Yeah?"

Haven suddenly spoke up, glancing at Doehring Cowart and said, "Then do you know how dangerous the danger you're talking about is?"

Doehring Cowart was slightly startled, then said in disbelief: "You...you can see me?"

Hai Wen said unhappily: "Of course, I was promoted to the Holy Land five years ago!"

“Crack—”

At this moment, the black dome on the cave ceiling suddenly cracked into three pieces.

Brilliant light bloomed from the cracks, and then filled the entire complex and intricate magic array pattern at an extremely fast speed.

Upon seeing this, Hai Wen was startled. He immediately flashed and appeared behind Lin Lei as if he had teleported, grabbing his collar with his big hands.

"There's no time to explain, let's go first!"
